While watching a .mkv with a DivX 5.2.1 video file I experience many lags in
the video, the sound and subtitles remain consistent. I use VLC for OS X.
Playing around with the settings for b-frames I achieved some improvements
(consistent subtitles, which were choppy as well), but the video still lags.
Playing the same files on XP with Zoom Player is no problem.
What can I do?
